Across New Zealand, asbestos-contaminated soil is a hidden risk on both residential and commercial land. Whether caused by past demolition, old fill material, or buried building waste, asbestos in the ground can impact construction, property value, and the safety of occupants.
Asbestos in soil can be easily overlooked — but it poses serious health risks, delays projects, and creates long-term issues if left unresolved. AR Plus offers expert site assessments and comprehensive remediation, enabling you to move forward with confidence.
There are several common causes of asbestos soil contamination:
Even small traces of asbestos in soil may trigger legal obligations and require licensed asbestos removal before further development can continue.
Prole Road, Tauranga
Old infrastructure can hide serious risks — and that includes asbestos. During repiping works on Prole Road, asbestos-containing cement sewage pipes were uncovered beneath the roadway. AR Plus was brought in to safely remove and dispose of the contaminated pipework, ensuring the job could proceed without health and safety delays.
Asbestos in soil may be out of sight, but it's not without consequences. Here's what can happen if contamination is left untreated.
If asbestos is discovered during earthworks, councils or WorkSafe NZ can issue a stop-work notice, halting your project until the site is cleared and certified.
Any digging, trenching, or groundwork can disturb asbestos fibres, exposing contractors to risk. Without testing, you may be unknowingly creating a health hazard and liability issue.
Dust and fibres can travel indoors via shoes, pets, garden tools, or wind. Even if your home is asbestos-free, contaminated soil nearby can introduce fibres over time.
Kids and pets spend more time close to the ground — playing, digging, or rolling in the grass. This puts them at higher risk of inhaling or ingesting asbestos-laden dust.
If contamination is uncovered during due diligence, it may delay or reduce the value of your sale. Early testing and removal show you’ve taken responsible action.
Wind and rain can carry fibres across your section — or into neighbouring land — increasing the scale of the problem and your liability.
Growing herbs or vegetables in contaminated soil creates potential hazards:
Even organic gardening practices can't protect you from contaminated soil — testing is the only way to be sure.
If you're planning a build, managing a property, or preparing land for sale, AR Plus can help identify and safely and efficiently remove asbestos-contaminated soil.
From backyard sections to large-scale developments, AR Plus is here to help you move forward with confidence.
We provide clear advice, full project coordination, and practical solutions that get the job done right, without unnecessary complexity or delay.
Our asbestos soil remediation service includes:
We’re trusted by homeowners, property managers, developers, and local authorities because we offer:
Even where visible fragments are present, asbestos testing is required. If the site has a history of demolition, fill material, or industrial use, it’s best to arrange a professional soil test before any groundworks begin.
If the land is commercial, being sold, or part of a development, you may have obligations under WorkSafe NZ or local council regulations to report asbestos contamination. AR Plus can help you understand and meet your compliance requirements.
Yes — it’s a valid concern. If your neighbour’s property has asbestos-contaminated soil, it’s possible that similar materials or past land use may have affected your section too, especially if the properties were developed at the same time or share boundary fill.
You don’t need to panic, but it’s wise to:
Early asbestos testing is a small investment that can prevent bigger problems down the line, especially if you’re planning to landscape, build, or sell.
Yes — while asbestos doesn’t absorb into plants, contaminated soil can result in dust on leaves or root crops. Inhalation while gardening and accidental ingestion are possible, especially without proper hygiene or soil testing.
If asbestos is confirmed, we can provide a free quote. Depending on the material’s condition and location, we may suggest removal, sealing, or regular monitoring. If removal is needed, our licensed team can manage that too — visit our Asbestos Removal page to learn more.
Yes — fibres can be brought inside on shoes, tools, or pets, or blown in through open windows. Over time, this can introduce asbestos indoors, even if your home itself is asbestos-free.
Yes. We can refill the cleared area with clean topsoil or match site levels to your requirements. We also work alongside your contractors to minimise project disruption.
Don’t wait for asbestos to hold up your plans. If you suspect past demolition, fill material, or unusual fragments on your property, get in touch.
